According to the Kubernetes design architecture, docker, kubelet, and kube-proxy must be deployed on minion. When APIServer is deployed in section 4.2, we have already distributed kubelet and kube-proxy to two minion, so we only need to configure the unit file of docker, kubelet, and proxy, and then start the service. For detailed configuration, see GetStartingKubernetes.5. Demonstration of Kubernetes Cont

Some of the technology frontier companies first-step practice is probably the most persuasive and reference value.

Kubernetes objects created in a cluster or clients that are accessed on the proxy cluster node are called internal users. To expose services to internal users, Kubernetes supports two methods: environment variables and DNS.
Environment Variable
When kubelet starts a Pod on a node, it sets a series of environment variables for the Pod container for the currently running Service so that the Pod ca
Docker enables more convenient management of single-machine container virtualization, where Docker is located between the operating system layer and the application layer;
Relative traditional virtualization (Kvm,xen):Docker can be more flexible to implement some of the application layer functions, while the utilization of resources is also higher
Relative application:Docker can better combine applications with more operating systems (mirroring), reducing the cost of deployment and
The Kubernetes network model is made up of four parts from inside to outside:
The network where the pod interior container resides
The network where the pod resides
Network for communication between pod and service
Network of communication between outside and service
It is recommended that you understand the network model of Docker before reading this article. Refer to the author's first two articles [

According to the Kubernetes resource model, QoS at pod level is divided into three levels: Guarantee, burstable, BestEffort, and we also set the standard for resource oversold according to the priority of the three levels corresponding to our application.
Our QoS standards for app settings:
Kubernetes comes with a component that uses guarantee
Important components and applications such as zook

Here we look at industry scenarios and related concepts.

Kubernetes is Google's Open source container cluster management system. It is built on Docker technology and provides a whole set of functions, such as resource scheduling, deployment operation, service discovery, expansion and contraction capacity, for containerized applications, which can be regarded as Mini-paas platform based on container technology. The purpose of this article is to comb the architecture, concepts, and basic workflows of
